President-elect Donald Trump has promised to leave his businesses in total, but ethics attorneys to former presidents say there are still problems if he leaves it all to his children. As the head of a business empire that spans at least 20 countries, Trump could be in violation of several conflict of interest rules, if he cannot separate the businessman from the president. It all has to do with the Emoluments Clause of the Constitution, which states the president cannot accept gifts or payments from foreign entities. Larry Noble, a lawyer serving both Republican and Democratic presidents, walks through the emoluments clause and other potential areas of conflict for the future president, including enforcement of those laws.
